BUILDING PLATES WITH EMBEDDED WIRE TIES CONNECTED BY ROD MEANS Hermann Klaue, Beyerlestrasse 1, Constance, German Filed .lune 4, 1964, Ser. No. 372,520 3 Claims. (Cl. 52--565) This invention relates in general to construction elements and to a method of constructing a building wall, and in particular to a new and useful building plate element such as an insulating plate having reinforcing metal elements embedded in the plate with a plurality of eyelet formations projecting outwardly from the surface of the plate `for anchoring two such plates together, and to a method of building a wall using such plate elements.

It has been known to constnuct a building wall using two insulating plates consisting of insulating board elements which are separated by distance pieces or spacer elements and wherein the space between the plate elements are lled with concrete. Such a wall may be of relatively small thickness and afford good heat insulation and will be relatively easy to produce. A disadvantage in such a construction and this method consists in that the insulating plates must be made at the building site. In addition, it is also necessary to provide special met-al reinforcements for this structure supporting walls.

In accordance with the present invention, there are provided plate elements, preferably insulating plate elements, which are formed with a reinforcing wire or grid having projecting eyelets or loop formations which permit the arranging of two such plate elements of this character in a spaced relation by reinforcing rod elements connected to the eyelets. By providing insulating plates of this character which are prefabricated and already equipped with a metal reinforcement and with projecting eyelets for securing the plates in position, it is possible to readily erect the plate elements at spaced locations and thereafter to fill the space lin between the plate elements with concrete.

A further advantage of such a construction is that the space between the plate elements may advantageously be interconnected by reinforcing rods which form reinforcements for the completed wall structure after the concrete has been poured. The reinforcements for the insulating plates may advantageously comprise wires or sheet metal strips which are bent in a wave formation and which include loop portions which are embedded in the plate and loop portions which extend outwardly for anchoring purposes. In some instances, a pair of such plates is integrally formed such as by casting and they are arranged in spaced location by wire elements which are molded therebetween. In those instances where the two insulating plates are formed as an integral part or piece or by plate elements which are formed together such as by welding at a prefabrication station, the building wall is erected when the elements are positioned at the site and concrete is poured between the plate elements. In those instances where the insulating plates are formed with projecting eyelets, two such insulating boards are arranged at spaced locations with the eyelets in opposed relationship. Thereafter, the boards are interconnected by diagonally positioned bracing rods which have hooked ends which engage in the eyelet formation on the insulating wall boards. Such an arrangement permits the formation of a laddershaped connection between the insulating plates which will be filled with concrete at the location of the building site.

The .inventive construction may also be employed where there is a desire to vary the thickness of the wall in a simple and easy manner. This may be done by merely changing the interconnecting position of the connecting rod elements which extend between eyelets of adjacent opposing wall boards. For example, for closely spaced walls of relatively thin thickness the connecting reinforcing rods may be oriented at sharp angles to permit the insulating boards to be spaced closely together.

In a further embodiment of the invention, an outer skin of metal is provided on the insulation plates which outer skin is connected by welding with loops of wire or strips which form eye-like projections extending from one side of the plate. In .some instances instead of a metal a plastic sheet or paper may be employed. The mechanical connection can be made by wire netting with which the wires or strips forming the eyes are connected by welding or gluing. The insulating plates themselves may advantageously consist of a clay ball formation and a concrete or adhesive mixture.

Accordingly, it is an object of this invention to provide an improved building construction element and a method of constructing a building wall.

A further object of the invention is to provide a building construction which includes an insulating plate having reinforcing wire means which forms a plurality of loops on a common surface thereof.

A further object of the invention is to provide a building construction element which includes a pair of insulating plates arranged in spaced locations and each having loop projections on opposing faces which are connected together by reinforcing rod elements and with reinforcing concrete disposed between the plates.

A further object of the invention is to provide a method of forming a building which comprises arranging a pair of insulating plates at spaced locations, interconnecting the insulating plates with reinforcing elements, and pouring concrete in the space between the plates.

A further object of the invention is to provide a building construction which is simple in design, rugged in construction and economical to manufacture.

Referring to the drawings in particular, the invention embodied therein in FIGS. 1, 2 and 3 comprises an insulating plate generally designated 20 which includes a wire or metal reinforcement generally designated 22 with oppositely extending transverse loops 2 and 2 embedded in a central core or body portion 4 of insulating material, such as burnt clay balls, adhesive or concrete mixture. An additional wire lattice is advantageously located toward the front or outer face `at 24. An outer skin 1 is advantageously formed of a material such as paper.

In accordance with the invention, each of the plates 20 is provided with the reinforcement 22 which includes loop formation 3 which extends outwardly from a common face 26 provided for anchoring a pair of the insulating plates 20 in spaced opposing positions as indicated in FIGS. 4 and 7. In FIG. 4 the plates 20 are indicated widely spaced and are held in a spaced orientation by means of reinforcing rods or connecting elements 7 having hooks at each end which are hooked into appropriate loops 3. The spaces 8 between the plates 20 are then filled with concrete to form the completed wall. In the embodiment of FIG. 7, the wall Iplate elements are oriented closely together for a thin wall construction by positioning the reinforcing rod elements 7 at a steep angle and connecting them to the appropriate loops 3 for achieving the desired spacing.

In FIG. there is indicated an alternate embodiment which comprises a single composite plate generally designated 28 formed such as by casting, and which comprises spaced vertical plate Wall portions 30 and 32 interconnected by integrally formed ribs 34.
